A student hands over two electronic devices and payment of a dollar for each at the Pure Loyalty Electronic Device Storage truck parked near the Washington Irving educational complex in New York on Sept. 27, 2012. Cellphones are banned in all New York City public schools, but the rule is widely ignored except in schools with metal detectors. Outside those schools, entrepreneurs park trucks where students drop off electronic devices before class and get them back at the end of the day. (Associated Press)
